<p>[QUOTE=&quot;desertgem, post: 789218, member: 15199&quot;]I certainly agree with this! The question is often &quot;Is this an original patina&quot;&nbsp; and then &quot; Is this patina stable at this stage so I can leave it alone&quot;. I don&#039;t use any kind of soap or detergents, as for their purpose, they have to have a degree of harshness. Even intact baby skin is more resistant to acids, alkali , and moisture than a copper surface. Using a solution with an unknown chemical makeup is more dangerous to coins than using one where the active chemicals are known or determined by experimentation and can be expected to react certain ways. I wouldn&#039;t apply acetone to a baby&#039;s skin , but I would to a coin surface. Like most, many decades ago, before I knew better, I harshly cleaned a coin with Bon Amai, because it didn&#039;t scratch plastic or glass in the lab like Ajax or such and was advertised as &quot;Scratch Free&quot;. Unfortunately it did scratch coins. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /></p><p><br /></p><p>As I said many posts ago, terms such as cleaning, dipping, conservation, are seen differently by many numismatists, and just their mention sets some people on edge. Many are experienced, knowledgeable ones, who see a different interpretation of the word itself, others are repeating advice from others and really don&#039;t understand there is a difference of degree. IMO. </p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
